The short answer

What W1 Black involves

A fully bespoke service for clients whose lives don’t fit a fixed schedule or a single location. There is no set length and no set format. The service is built entirely around you, wherever you are.

Your lead coach assembles and manages a hand-picked team of specialists, including physiotherapy, psychology, clinical diagnostics and, where relevant, Cedars Sinai physicians. They all work to one plan with one point of contact. “Coordinated specialist care, with coaching at the centre holding it all together.”

Your programme travels with you. Leigh can join you on the road, at home or abroad, for business trips, extended stays or time at a second residence, so training, nutrition, sleep and recovery hold steady when your schedule doesn’t. Between visits, remote coaching and planning keep everything on track across time zones. Privacy is built into how we work, with your family, your team and your household staff where needed. W1 Black suits clients managing complex health situations, those whose work and life involve constant travel, and those who simply want the most complete service we offer. Places are limited.

How it works

How the relationship works

Getting started

Before the first conversation, it helps to know who currently looks after your health, what recent testing or screening you have had, how and where you travel, and what you are trying to protect or change over the next ten years. Bring existing blood work and scan results if you have them.

During your sessions

Step 1: A conversation, not an application form

W1 Black starts with a conversation about what you are actually trying to protect or change, and how your life and travel really run. It is a mutual fit question. Places are limited, and the service only works where the client genuinely wants the coordination.

Step 2: The full picture is established

A Vitality Profile across the eight elements of health and performance, plus clinical diagnostics: an advanced blood panel, DEXA scan, biomarker analysis and a physician consultation, working with physicians from Cedars Sinai and The Mayfair GP. Existing practitioners are brought into the picture rather than worked around.

Step 3: One team, one plan

Your lead coach assembles the specialists you need, from physiotherapy to psychology, and they all work to one plan with one point of contact. Training, nutrition, sleep and recovery are planned as one system alongside whatever the physicians and specialists advise.

Step 4: Wherever you are

Sessions run at UNTIL Marylebone, at home, or wherever you are, and Leigh can travel with you for business trips, extended stays or time at a second residence. Between visits, remote coaching and planning keep everything on track across time zones.

Step 5: Review against measures, not feelings

Diagnostics are repeated at agreed points and the long-term plan is reviewed against them. Over a period of years that is what separates a programme that worked from a programme that felt like it was working.

After your sessions

The plan is held and adjusted continuously rather than at fixed review points, and diagnostics are repeated at agreed intervals so the long-term picture is judged against the same measures. Any medical advice remains with the physician and your GP.

FAQ

W1 Black
questions

How is W1 Black different from Sprint, Build and Sustain?

Those programmes have a set length and run from Marylebone, with remote coaching between sessions. W1 Black has no set length and no set format: your lead coach assembles a hand-picked team of specialists around one plan, clinical diagnostics are built in as standard, and the programme travels with you wherever you are.

Can Leigh travel with me?

Yes. Leigh can join you on the road, at home or abroad, for business trips, extended stays or time at a second residence, so training, nutrition, sleep and recovery hold steady when your schedule doesn’t. Travel arrangements are agreed in conversation, and remote coaching keeps everything on track between visits.

Does Leigh provide the medical care?

No. Leigh is a performance coach, not a clinician. Blood work, scanning and physician review are delivered by the physicians from Cedars Sinai and The Mayfair GP that we work with, and any medical advice or onward referral sits with them and with your GP. What your lead coach owns is the coordination and every coaching decision that follows.

Can I keep my existing GP, physio or specialists?

Yes, and that is usually the sensible route. The point of the service is not to replace the people who already look after you: it is to join them up, so the training reflects what your physiotherapist is working on and your nutrition reflects what your blood work shows.

How private is it?

Entirely. Privacy is built into how we work, with your family, your team and your household staff where needed. Nothing is published about who uses the service, and the coordination happens directly rather than through an office.
